' This invention relates to rushers, and with regard to certain more specific features to Crushersfor such materials as limestone, shale, iron ore', coal, gypsum, asphalt rock 5. and similar materials which may contain moist impurities such as clay or mud.

Among the several objects of the invention may be noted the provision of a simple and i rugged Crusher, the provis1on of means for preventing detrimental clogging of such a Crusher, the provision of means for easily adjusting the relationship between various elements of said Crusher, the provision of a crusher of the class described which is adapt# ed to be fitted under a storage hopper, and a crusher of the class described which provides transporting means for bringing the substance to be crushed from. a considerable distance to the Crusher, said means being formed integrally with said crusher. Other objects will be in part obvious and in part pointed out hereinafter. p

The invention accordingly comprises the features of construction, combinations of elements, and arrangements of parts which are exemplified in the structure hereinafter described, and the scope of the application of which will be indicated in the following h claims.

In the accompanying drawings, in which is shown one possible embodiment of this invention,

Fig. 1 is a rightside elev-ation `of the crusher;

Fig. 2 is a'front elevation, parts being broken away; A

Fig. 3 is an ideal longitudinal section taken approximately on the line 3 3 of Fig. 2' and 7Fig. l is a plan view of a pair of end driven plates linked together.

Similar reference characters indicate corresponding parts throughout the several views of the drawings.

Referring now to the drawings there isl illustrated at numeral 1 a frame comprised of side castings 3, a cover 5 and a hopper chute 7.

F orwardly bolted at 9 between the two side castings 3, is a cross channel beam 11 lta'ry crusher.\ Ato receive the hammers between them and nel beam 11 is boltedanother cross beoam or `brace casting 10 bolted sidewardly at points 12. Thiscasting 10 also aids in holding the frame side castings 3 together. Rearwardly a frame 13 serves the same purpose. The' frame 13 has its central opening normally closed by a door 15 which may be opened'for purposes of inspection Awhen occasion demands. It is to be understood that the beam 11 may be dispensed '-with, under certain conditiona The cover 5, itself an assembly of cornponent castings, serves to close the device and tie the end castings together at their upper portions. y

The side castings 3, the frame 13 including its door 15, and the cover 5 serve to enclose va rotating set of hammers 17 mounted between discs y19 said assembly forming a ro-. The disc faces are machined are provided with through-bolts 21 for tightening the hammers. Other holes 23 in the discs permit adjustment of eachl set of ammers' as wear on said hammers takes place.` They adjustment is radial so that as the hammers wear shorter, compensation may be permitted.

The discs and hammers are mounted upon a shaft 25 running cross-wise of the machine. This shaft is borne in ring-oiled bearings 27 at each side of the device. The bearings are cast with the end castings and are of generous proportions as isthe whole machine. On the left end of the shaft, and outside of the machine, is borne a ily-wheel 29, and on its right end a driving coupling 31.l

Cradled below the rotary hammers 17 are cage bars 33 cast en bloc. They are held in position by means of bolts 35 and cage liners 37. The liners are bolted to the side cast'- ings 3 and serve as end supports for the cage bars. They also protectlfrom abrasion the surfaces to which they are bolted. These bars provide a bed and serve to permitV only material which has been crushed down to a proper size to pass out of the bed or base of the machine.

At the ends of the hammer-disc or rotary crusher,assembly, or rotor, are placed end liners 39. These are bolted to the end-casting 3 and cover 5 and serve as renewable safeguards against abrasion of said parts; The chute 7 is lined with liners 14 at points subjected to abrasion.

Mounted in and between bearing blocks 47 is an u per cross-shaft 45 upon which is mounte a plurality of supporting rolls 55. The rolls 55 may be varied in number and position to suit certain types of breaker plate or endless conveyor chains to be mounted thereon.

A lower cross shaft 57, similar to the upper cross shaft 45, extends laterally between the side castings 3. It is mounted in adjustable bearing blocks 16 at each side of the machine. The blocks 16 are slidably arranged in substantially horizontal guides 18, formed in sidewardly placed castings 20.

fThe castings 20 may either be formed integrallv with the side castings 3 or be bolted thereto. lt is clear that the shaft 57 may be moved forwardly or rearwardly by slidin" the bearing blocks 16 in their guides 18. -Qubstantially horizontal elongated passages 22 see Fig. 1) are formed in the side castings 3 in order to permit said movement of the lower cross shaft 57. A proper tongued and grooved formation of the bottoms of the guides prevents sidewise motion of the blocks and yet permits their removal at one end of their travel.

Each of the levers 28 is pivoted to a side casting 3 at the upper front portion of said casting. Each reaches downwardly and embraces a portion of its respective bearing block 16 atan opening 26. The openings 26 are of such length that, if the levers 28 be swung forwardly or rearwardly, the blocks 16 may traverse their complete predetermined paths. Each opening perm8it's ample swing of its corresponding lever 2 It is clear at this stage of the description, that by swinging the levers 28 upon their pivot rod 30a, that the lower cross shaft 57 may be moved forwardly or rearwardly of the crusher, inasmuch as its translatory motion is governed by the translatory motion of the bearing blocks 16 in their guides 18.

In order to swing the levers 28 on their pivot rod 30a, sideward adjusting rods or bars 32 are pinned to bosses 34 formed with the levers 28. A through-bolt or shaft 36 serves to pin each bar 32 to its lever 28 and nuts are provided on the bolt ends, whereby the bars 32 and levers 28 may be drawn tightly together after an adjustment is made. The levers 28 and bars 32 are drawn against the side castings 3. The bars 32 pass forward of the machine in under the bearings 27, and through lurgs 38 formed integrally with the rearwa d end of the machine. These side bars may govern the swing position of the levers 28 and other parts to be described. Fig. 3- shows one of two slots 42 formed in the side castings 3 which accommodate the forward and rearward motion of the clamping through-bolt or shaft 36. The shaft 36 reaches laterally across the machine (Figs. 1 and 3), as does the pivot rod 30a. I

Reference to Fig. 3 indicates that the cross shaft 57 has fastened thereto end sprockets v59. These are placed just within the limits of the side castings 3.

Over the sprockets 59 of the lower shaft 57 and the supporting rolls of the upper shaft 45 is placed a beltlor chain or endless chain conveyor 67 comprising links or breaker plates 69 formed of manganese steel or other Wear or impact resisting material. Each link 69 comprises a bar at the ends and on one side of which are formed outwardly jutting gudgeons 71 adapted to ride between the teeth of the sprockets 59 and to be driven thereby. These gudgeons are properly rounded to kinematically mesh with proper teeth on the sprockets.

On one edge of the links 69 are formed projections or hinge portions 73. On the other edge are formed similar projections 75' in staggered relationship to the said portions 7 3. Thereby a series of the links 69 (see Fig. `4) may be interfitted. Through the various sets of interitting hinge portions 73 and 75 are bored or otherwise formed aligned holes 77 adapted to receive a link pin or rod 79. The holes 77 pass through the said gudgeon 71 and are therein countersunk. The rod 79 is riveted over at the countersunk holes as the chain is made. It is formed flush with the gudgeon ends.

It is evident that the gudgeons serve to mesh with the sprockets 59 and may be driven thereby. Hence the chain is driven if the sprockets are rotated as indicated in Fig. 3. The supporting rolls 55 act as idlers and support the chain at its upper end. The diameters of rolls 55 are approximately that of the sprockets at the base of their teeth. The gudgeons ride free of .the rolls 55. The linked chain 67 and the hammers 17 form the crushing elements of this machine. The links cover the width of the hammer rotor in projection'. tendant impact of the crushing operation the chain 67, or breaker plates 69 are backed by a suitable rugged platen 81. This platen 81 is pivoted to the end castings 3 by the said pivot rod 30a which forms the pivots for the outside adjusting arms 28 (see Figs. 1 and 3). It backs the chain of breaker plates at the point of impact. It may be adjusted to different required degrees of slope of the breaker plates, or to different degrees of wear in In order to withstand the atllU said members by means of the said shaft 36 whichpasses through slots 83 in flanges 85 of the platen and through slots 42 in the side castings 3. Outside of the side castings 3 the shaft 36 serves normally to clamp the levers 28 and rods 32 together4 and t-o the said cast-y ings 3. Hence it is clear that when the lower shaft 57 is adjusted to position by means of the rods 32 and levers 28, after loosening shaft 36, that the backing platen 81 is automatically adjusted by means of the said rod for purposes of equalizing. loads, and receives its energy from some external prime mover or other source (not shown).

The shaft 57 is driven in a clockwise direc-l tion as viewed in Figs. 1 and 3. It is clear that, due to the universal drive described, the shaft 57 may be driven in .any of its adjusted positions and thereby drives the breaker plate chain downwardly at the point of impact.A The hammers 17 rotate counter-l clockwise as viewed in Figs. 1 and 3. Theirl linear s eed at the crushing point is preferablysu stantially higher than that of the` moving plates, whereby material is carried down to the gra-tes.

In order to bring material to the machine,

there is provided a hopper 121 supported by columns 123, the latter also supporting beams 125. The beams 125 support a plurality of rotatable rolls`127 and also rails 129, the upper faces of which rails are tangential to the roll peripheries, the purposes of which is to cause the rolls 127 and rails 129 to slidably support an extension reach 131 of said breaker plate chain 67, the upper face of the reach 131 facing the lower outlet of the hopper 121 and forming a horizontal portion `for receiving material to be crushed.

At one end of the beams 125 is supported a set of slidably adjustable bearings 133 for a last set of rolls 135 over which rolls the Chain 67 of breaker plates passes. The rolls 135 and thesprockets 59 are joined by a lower reach 137 of said chain 67.

The-operation of the machine is as follows:

Material is fed down into the hopper 121 and is forced by gravity down on the reach 131 of the chain 67. The movement of the chain in the direction indicated'in Fig. 3 carries the material into the hopper 7. Gravity carries it downward on the sloping breaker plates into the paths of the rapidly rotating hammers 17. These hammers impact the lumpy material against the slowly l and downwardly moving breaker plate chains thereby breaking most of the material down to a size lsmall enough to pass the cage bars 33. That which has not been broken small enough can not pass the cage bars and consequently goes around with the hammers for a second crushing. The liners 14 and 37 protect the frame against wear. The breaker plates transmit the force of the blow given to them, to the backing platen 81.

After the links of the chain have performed their feeding and crushing operations they pass over the sprockets 59 and return by way of reach 137 to rollers 135.

Reference to Fig. 2 indicates that the shaft 59 and the shaft 45 are connected by a chaindrive 139 of a one to one ratio. By this means the upper set of rolls 55 serve to feed the breaker plates down into` the Crusher without too much dragging action as would ordinarily be had if the chain had, withoutsome type of anti-friction means, to be pulled around the angle indicated at X in Fig. 1.

One of the advantages ofthe invention is that the chain .of breaker plates, which is already required to be exceedingly rugged in order to withstand the crushin operation is also used for vthe heavy duty o` transporting material from the hopper 121. yBy thus combining elements the necessity is eliminated fora second expensive machine having many duplicate parts. For instance, the rolls 55 serve the duty of feeding the chain from the hopper 121 and alsovintothe Crusher. The same chain performs a crushing operation that performs feeding. The same adjustment feeder 133 serves a feeder and the Crusher.

In view ofthe above, it is believed that the various features of thisinvention will be clear without further elaboration, and it will be seen that'with the apparatus herein described, the several objects of the invention are achieved and other advantageous results attained. l
